
Vehicles with a smart entry & start system
The standard battery life is 1 to 2 years.
●
● If the battery becomes low, an alarm will sound in the cabin when the engine
stops. (P. 742)
As the electronic key always receives radio waves, the battery will become
●
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. (P. 691)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
You can replace the battery by yourself (P. 691). However, as there is a
danger that the electronic key may be damaged, it is recommended that
replacement is carried out by your Toyota dealer.
● To reduce key battery depletion when the electronic key is to not be used for
long periods of time, set the electronic key to the battery-saving mode.

ft.) of the following electrical appliances that produce a magnetic field:
• TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
■ If a message regarding the state of the electronic key or engine switch
mode, etc. is shown

without turning off the engine switch or other passengers from unintentionally
taking the key out of the vehicle, etc., a message that prompts the user to
confirm the state of the electronic key or engine switch mode may be shown
on the multi-information display. In those cases, follow the instructions on the
